Abstract: A tire pressure monitoring system (TPMS) sensor and a communication method are provided. The TPMS sensor includes a microcontroller unit, a pressure sensor electrically connected to the microcontroller unit and configured to measure an internal air pressure of a tire and a receiver electrically connected to the microcontroller unit and configured to receive at least one communication signal. The receiver includes a magnetic sensor configured to detect a modulated low-frequency electromagnetic carrier signal as a first communication signal and output an encoded measurement signal based on the detected modulated low-frequency electromagnetic carrier signal. The TPMS sensor further includes a demodulator configured to convert the encoded measurement signal into a data signal and output the data signal to the microcontroller unit.

Abstract: Embodiments may provide a system, a wheel localizer, a wheel localization device, or methods for locating a position of at least one wheel out of a plurality of wheels of a vehicle. In one embodiment, a system comprises a detector that obtains information related to a reference magnetic field in which the at least one wheel rotates, an antilock braking system (ABS) unit that obtains information related to angular rotations of the plurality of wheels, and a locator that determines the position of the at least one wheel based, at least in part, on the information related to the reference magnetic field and the information related to the angular rotations of plurality of wheels, where the position comprises a wheel location from among the plurality of wheels. The reference magnetic field may be the earth's magnetic field.
